Modular ratios for unbound granular pavement layers
Unbound granular pavement layers show a characteristic increase in moduli from the subgrade to the surface. The ratio of moduli between successive layers provides a direct and effective measure of pavement quality that makes due allowance for site conditions and seasonal effects beyond a contractor’s control. The modular ratio is therefore an effective indicator for performance-based specificat...
متن کاملCalibration of Pavement ME Design and Mechanistic-Empirical Pavement Design Guide Performance Prediction Models for Iowa Pavement Systems
The AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG) pavement performance models and the associated AASHTOWare® Pavement ME Design software are nationally calibrated using design inputs and distress data largely from the national Long-Term Pavement Performance (LTPP). Further calibration and validation studies are necessary for local highway agencies’ implementation by taking into acc...
متن کاملUse of Pavement Management Information System for Verification of Mechanistic-Empirical Pavement Design Guide Performance Predictions
The performance models used in the Mechanistic-Empirical Pavement Design Guide (MEPDG) are nationally calibrated with design inputs and performance data obtained primarily from the national Long-Term Pavement Performance database. It is necessary to verify and calibrate MEPDG performance models for local highway agencies' implementation by taking into account local materials, traffic informatio...
متن کاملEmpirical Comparison of Statistical Pavement Performance Models
We conduct an empirical comparison of nine representative statistical pavement performance models, which have been estimated using serviceability data from the AASHO Road Test. The purpose of the study is to understand the effect of different statistical assumptions and estimation techniques on the models’ predictive capabilities. The study consists of using the models to predict the serviceabi...
متن کاملCharacterization of Cementitiously Stabilized Subgrades for Mechanistic-empirical Pavement Design
Pavements are vulnerable to subgrade layer performance because it acts as a foundation. Due to significant increase in truck traffic, pavement engineers are challenged to build more strong and long-lasting pavements. To increase the load-bearing capacity of pavements, subgrade layer is often stabilized with cementitious additives. Thus, an overall characterization of cementitiously stabilized s...
